Even trough all this ****s in 4.3.4, resto druids are actually pretty good... But only if you have enough skill to run away every now and then..
In PvE it is actually easy to be best healer especially in aoe fights.. (well atleast me )
But if you want to PvP as resto druid you beater team up with some OP class that can do crazy dmg..
My point is resto druids are good if the fight is short.. If fight last more then 5 minutes its probably a lost for resto druid team.. :S
About BGs, its easy, nice heals, enemy rarely attack you, only pro ones. but you can run away easy.
If you love it then nothing should stop you from playing it.

depend on skills if u know than it's realy good class for you,if u don't know u have a hard way to learn...

so I see ppls says paladins are better than druid let's see... proc's and cons

holy paladin can regenerate mana with divine plea, big amount for short time + wings + bubble as def cd's, hand of freedom help's a lot... cc-s stun dispealble not so effective, rebuke is good but risky require close distance

massive battleground healing - rdruid is fine, in terms of holding on heavy pressure - 50/50.
still it is viable, and pretty fun to play, i really enjoy it.
still more fun, than those **** paladins.
if you want to top healing pretty much everywhere - roll a shaman, but as it is for me - shaman healing is harder, than druids.
priests are cool too, with they're absorbs...
expect HEAVY and i mean HEAVY OOM it really takes some time to regenerate mana, and don't forget that you must be out of combat, to drink some....

Resto Druids were quite bad on retail in this patch, but for some reason they are managing on molten. I can't put my finger on why. Sure the occasional skilled one would appear on retail, but that's not common.

I mean, it was basically like this in arena: "Oh look a resto druid in arena, free win".
